En innkapslet bryterkjemikalieblanding anvendt i en olje- og gass-stimuleringsoperasjon omfatter: et bryterkjemikalium og et pinhull-fritt belegg av en ionisk og kovalent fornettet nøytralisert sulfonert elastomer polymer med en tykkelse på 2-80 pim, avsatt på overflaten av bryterkjemikaliet, og hvor polymeren innkapsler bryterkjemikaliet og polymeren er permeabel i forhold til bryterkjemikaliet og ikke-reaktivt i forhold til dette.An encapsulated switch chemical composition used in an oil and gas stimulation operation comprises: a switch chemical and a pinhole-free coating of an ionic and covalently crosslinked neutralized sulfonated elastomeric polymer having a thickness of 2-80 µm, deposited on the surface of the switching chemical, and wherein the polymer encapsulates the switch chemical and the polymer is permeable to the switch chemical and non-reactive to it.
